An analytic function of a complex variable \(z = x + iy\;\left( { i= \sqrt { - 1} } \right)\) is defined as
f(z) = x2- y2 + iψ (x, y),
where ψ(x,y) is a real function. The value of the imaginary part of f(Z) at z = (1 + i) is _______ (round off to 2 decimal places).
Enter numerical value using the virtual keypad. Round off where necessary.
